Abstract
The early and late stages of gamma-ray bursts are studied in a statistical analysis of the large sample of long BATSE events. The primary peak is used as the boundary between the early and late stages of emission. Significant differences are found between the stages : the early stage is shorter, it has harder emission, and it becomes a smaller fraction of the total burst d uration for burst groups of decreasing intensity.
